We have just finished our latest new conversion commission, which was for a Hornby BR 4-4-0 Class T9. Due to the limited space between the inside of the splashers and the front tyre face of the wheel, we converted this model to EM use our EMF wheel profile (the same setup we use for Pendon) as a result there has been no need to make any changes to the body of the model to clear either the wheels or the crank pins. The only problem if you call it that, is the pick-ups on the tender. These are only long enough for 'OO' and for any other gauge will need to be modified as required.

Gear Lab is a collection of gear data calculators in the form of an iPhone app that can be used with Worm gears, Helical gears and Spur gears.

However, it can be used for the same type of gears from other sources.

Having now looked at our new bank changes for the processing of cheques/postal orders. We have taken the decision that we will now have to introduce a £5.00 surcharge charge for all orders that are paid for either by cheque or postal order. We are sorry to have to take this action but it has been force on us by the increase in bank charges for these items.

This new charge will only apply to cheque/postal order payments and will be introduced from Monday 14th October 2013. Any orders that are received from this date on, that do not meet this rquirement will be returned.
